UHF- Transmitter
The product meets the requirements of the current European and national guidelines for
electromagnetic compatibility (EMC). Conformity has been established and the relevant
statements and documents have been deposited at the manufacturer.
Mode of Operation
The transmitter is able to transmit coded signals to a matched receiver via radio transmission.
The operation corresponding to these signals depends on the receiver and its wiring.
It should be noted that for applications that could put human life at risk, by using
radio connection there is always present a potential hazard due to extraneous
disturbances.
It is forbidden to modify or change component parts of the product !
Range of operation
The system is designed for large operating range up to over 100 meters and even obstructing
walls or steel reinforced constructions can be penetrated.
The range may be reduced for the following reasons:
• Buildings, vegetation or any other objects will substantially reduce the operating range.
• The distance between the antenna and the human body or other conducting objects (e.g.
Earth) may influence the working range.
• "Background electrical noise" could be relatively high so that the signal-to-noise-ratio
decreases and therewith the range.
Also other devices, with similar operating frequency, located within the neighbourhood may
disturb the receiver.
• Operating the receiver next to inadequately shielded electronic boards or other devices (e.g.
PC's) that produce electromagnetic radiation, can substantially reduce the range of operation
and could result in an apparent intermittent operation.
• It is forbidden to modify, change or manipulate component parts of the product!
Description of Operation
The transmitter SHT-7 C and SHT-7 CD are able to transmit up to 3 different signals to
matched receivers.
SHT-7 CD is manufactured with a gasket between the pieces of case and an additional
keyboard overlay.
SHT-7 C1 and SHT-7 F1 act with only 1 Button, to avoid faulty operation in dedicated
applications.
SHT-7 F1 has an keyboard overlay to avoid uncontrolled operation.
Each transmitter is able to control a number of receivers.
